<h2>Parameters</h2>
<dl>
<dt><i>Source</i> [in]</dt>
<dd>
<p>Specifies the register source to query.</p>
<p>The possible values are listed in the following table.</p>
<table>
<tr>
<th>Value</th>

<p>Fetch register information from the target.</p>

<td>
<p>Fetch register information from the current explicit <a href="#Bookmark1375">register context</a>.</p>
</td>
</tr>
<tr>
<td>
<p>DEBUG_REGSRC_FRAME</p>
</td>
<td>
<p>Fetch register information from the current scope's register context.</p>

</table>
<p> </p>
</dd>
<dt><i>Count</i> [in]</dt>
<dd>
<p>Specifies the number of registers whose values are requested.</p>
</dd>
<dt><i>Indices</i> [in, optional]</dt>
<dd>
<p>Specifies an array that contains the indices of the registers from which to get the values.  The number of elements in this array is <i>Count</i>.  If <i>Indices</i> is <b>NULL</b>, <i>Start</i> is used instead.</p>
</dd>
<dt><i>Start</i> [in]</dt>
<dd>
<p>If <i>Indices</i> is <b>NULL</b>, the registers will be read consecutively starting at this index.  Otherwise, it is ignored.</p>
</dd>
<dt><i>Values</i> [out]</dt>
<dd>
<p>Receives the values of the registers.  The number of elements that this array holds is <i>Count</i>.  See <a href="#Bookmark906"><b>DEBUG_VALUE</b></a> for a description of this parameter type.</p>
</dd>
</dl>
<h2>Return value</h2>
<p>This list does not contain all the erros that might occur.  For a list of possible errors, see <a href="#Bookmark909"><b>HRESULT Values</b></a>.</p>
<table>
<tr>
<th>Return code</th>
<th>Description</th>
</tr>
<tr>
<td width="40%">
<dl>
<dt><b>S_OK</b></dt>
</dl>
</td>
<td width="60%">
<p>The method was successful.</p>
</td>
</tr>
<tr>
<td width="40%">
<dl>
<dt><b>E_INVALIDARG</b></dt>
</dl>
</td>
<td width="60%">
<p>The value of the index of one of the registers is greater than the number of registers on the target computer.  Partial results might have been obtained; those registers that could not be read will have the type DEBUG_VALUE_INVALID.</p>
</td>
</tr>
</table>
<p> </p>
<h2>Remarks</h2>
<p>If the return value is not S_OK, some of the registers still might have been read.  If the target was not accessible, the return type is E_UNEXPECTED and <i>Values</i> is unchanged. Otherwise, <i>Values</i> will contain partial results and the registers that could not be read will have type DEBUG_VALUE_INVALID.  Ambiguity in the case of the return value E_UNEXPECTED can be avoided by setting the memory of <i>Values</i> to zero before calling this method.</p>
<p>The method <a href="#Bookmark604"><b>GetValues</b></a> performs the same task as this method but always uses the target as the register source.</p>
<p>For an overview of the <a href="#Bookmark596"><b>IDebugRegisters</b></a> interface and other register-related methods, see <a href="#Bookmark218">Registers</a>.</p>
